Re: Variacs Wanted

Original poster: Terry Fritz <teslalist-at-twfpowerelectronics-dot-com>


The China variacs are "cheap" and check them all out if you get 
one....  But they really do "work"...  No match for the 100+ year life of 
the expensive American ones.  But they will run a coil just fine.  Check 
Ebay first since really nice variacs go there for very good 
prices!!!  That's where I get mine....
